i may be wrong but i think A. sorry if im wrong

Answer:

5

Step-by-step explanation:

√((5-2)^2 + (-3-1)^2) = √(9+16) = 5

Answer:

5 units

Step-by-step explanation:

To Find :-

Solution :-

Using Distance Formula ,

> d = √[ ( 1 +3)²+ ( 2-5)² ]

> d = √[ 4² + 3² ]

> d = √ [ 16 + 9 ]

> d = √25

> d = 5

Answer:

x=7

Step-by-step explanation:

You know that the 17x+11 and 19x-3 are equal because they are corresponding angles. Then, you would solve it like an algebraic equation:

17x+11 = 19x-3

Move all the like terms onto one side.

14=2x

It would be easier to look at if moved the x onto the left so it would look like this:

2x = 14.

Then divide by 2 and your answer should be 7.

Answer:

- 13x² + 7x + 6

Step-by-step explanation:

- 4x² + 6 - (9x² - 7x) ← distribute by - 1

= - 4x² + 6 - 9x² + 7x ← collect like terms

= - 13x² + 7x + 6

Answer:

C = 37.68 (using 3.14)

if you use a calculator you would get 37.69911184

Step-by-step explanation:

C = [tex]2\pi r[/tex]

C = 2(3.14)r

C = 6.28(6)

C = 37.68 (aprox)

Answer:

a) x = 5 and y = 2

b) x = 4 and y = 4

Step-by-step explanation:

Here, we want to solve the simultaneous equations by graphing

We shall be using an external graphing tool for this

The point at which the lines intersect represent the solution to the equation

please check attachment for the plots

For the first equation, we have the solution as;

x = 5 and y = 2

For the second, we have;

x = 4 and y = 4

Answer:

The girls played 20 games.

Step-by-step explanation:

To fins how many games played. Divide the percentage lost by the number of games lost. Then divide the quotient from 100% to find how many games were played.

15% ÷ 3 = 5

100% ÷ 5 = 20 games

Answer:

b. 40

Step-by-step explanation:

The value of x (exterior angle) is equal to half of the difference of given arcs

(100 - 20) ÷ 2 = 40

Answer:

-3 I believe is correct. Tell me if I'm wrong

Step-by-step explanation:

Answer:

$3.13 after you add the tax.

Answer:

I believe the measure of the sum of interior angles of  square is 360 degrees, and we know that all the angles are equal to 3x. You'd set up the equation to look like 3x+3x+3x+3x=360

simplify that, and you get 12x=360

this means x= 30

Answer:

5x+2

Step-by-step explanation:

Answer:

5x + 6

Step-by-step explanation:

=========================================================

Explanation:

Point Q is located at (0,w). We see that x = 0 and y = w.

So we'll replace x with 0 and y with w. Then we solve for w.

2x+3y = -12

2(0)+3(w) = -12

0+3w = -12

3w = -12

3w/3 = -12/3

w = -4

In the second to last step, I divided both sides by 3 to undo the multiplication of 3. Saying 3w means "3 times w".

Side note: The point Q is the y intercept as this is the location where the diagonal line 2x+3y=-12 crosses the vertical y axis.

Answer:

x = -17/2

Step-by-step explanation:

2(x+13)=9

2x+26=9 (multiplying 2 with both the numbers)

2x=9-26 (shifting 26 on the other side of the equation changes its sign)

2x=-17

x=-17/2 (2 is in multiplication form, so shifting on the other size changes it into division)

Answer:

2 x x + 2x13=8

or,2x+26=9

or,2x=9-26

or,2x= -17

or,x= -17/2

so, x= -8.5

Answer:

x=8

Step-by-step explanation:

Angle S and R are remote interior angles which means that they would add up to equal angle RQK.

78+5x-1=15x-3

Combine like terms

77+5x=15x-3

Add 3 on both sides

80+5x=15x

Subtract 5x on both sides

80=10x

Divide 10 on both sides

x=8

Answer:

Step-by-step explanation:

[tex]24a-3(2a-5)=51[/tex]

Step 1: Let's solve first so we can order  it later.

[tex]24a-6a+15=51\\18a+15=51\\-15 -15\\\18a=36\\\\[/tex]

Divide 18 both sides.

[tex]a=2[/tex]

Ok so we have everything solved answer: a=2.

Now we need to order.

Step 1. Distribute 3.

Step 2. Combine like terms 24a and 6a.

Step 3. Subtract 15 from both sides.

Step 4. Divide both sides by 18.

Hope this helps :)

Answer:

1

Step-by-step explanation:

slope is equal to "rise over run"

or = rise / run.

if you mean by  

a rise and a run of 4;

rise = 4 & run = 4,

then the slope is 4 / 4 = 1.
